摘要
本文应用钡离子选择电极和分光光度法测定钡离子的消失速度以监测过二硫酸盐和溴化物之间反应的速度,发现在缺少抗坏血酸时,pH 保持在3. 9左右,铜离子浓度在0～1ppm 范围内,基本观察不到铜对上述反应有明显的催化作用。
An Baric-ion Selective electrode and spectrophotoncetry are used to measure the rate of disappearance of Baric ion.gt is observed that in the absence of ascorbie acid(and the pH value is kept at 3. 9) no copper in the 0～1ppm concentration range catalyses the reaction in contrast to earlier studies.
